That Nazi gold train - just a thought

No doubt it will cost a lot of money to dig down 8-10 metres to find the train in Poland, and it might take a lot of legal wrangling to get the job done to everyone's satisfaction.

Surely someone could use some high tech system or even low tech system, to suspend a camera on a wire - like keyhole surgery? How about even sending a drone down there to fly through the length of the tunnel? Oh well, I was just saying. And there is a medical robotics expert in Wroclaw - I have his card.
